    Finally getting into some deeper data analysis now that I can get brake pressure data. Throttle and steering are easier to analyze and improve without a ton of data.

    This is a very helpful video to setup Race Studio for AIM users... https://youtu.be/8bcPAwmzkM4?si=nY_IB_Q-KIK5lxmV

    This is from my last event at ECR. I had two big time deltas. One was just a matter of rolling more speed into the corner. This one was more interesting. The delta just started climbing from this point. It was not obvious looking at speed and long/lat acceleration. This is where the MK60 brake pressure data is critical The brake trace on top was very different. The green line (fast lap) was a relatively smooth ramp up and then release with less trail braking than the red line.

    The red line is I ramped up the brakes slower, perceived to not slow the car enough and then got on the brakes again. That should unbalance the car more than the green trace. Lesson learned is I really need to be more precise in my braking and that is where the time is. That was my theory but it helps knowing it.

      Carbon fiber brake deflectors finally done! Geez...I'm so behind! Here is info from my initial test with an aluminum deflector -

      I did some testing this past weekend with some send cut send made brake deflectors. Pretty simple, just need to notch the upper corners for clearance. Mounted to the control arm with a heavy duty zip tie. I've seen some deflectors available but never seen any actual results. Love that when tuners sell stuff that they don't know

      Simple install with a zip tie. I had a 65-70 improvement with the deflectors with a flat splitter. This time, I am using a splitter with tunnels. Honestly, got a lot lucky that the deflectors line up perfectly with the tunnels. Hopefully the deflectors don't interfere with low pressure zone at the leading edge of the tunnels.

      More testing this weekend to see if the tunnels increase brake cooling.

        You could 3D print something like my design which tends to direct air better than your video, if my testing also holds. Then if you like that, make a carbon version

          I like it! I'm pretty sure this would get much better results but I don't need a TON of cooling. I already don't have a lot of pad wear and I'm worried about overcooling the brakes. In fact, I will likely have to remove them during cooler weather.

          I'll have to look into that duct for my next track project...could be a G87 M2. Do you have a file for that duct? Or let me know if you're willing to print a pair.
